Coupled 3D Dislocation Modeling at Nano- and Micro-Scales

Jaehyun Cho

The performance of crystalline materials varies depending on the considered scale. To understand the size dependence of materials properties, the interaction and evolution of defects are essential. As such, the role played by dislocations is crucial for mo ...

Mobility law of dislocations with several character angles and temperatures in FCC Aluminum

Jean-François Molinari, Guillaume Anciaux, Jaehyun Cho

We study the mobility law of dislocations in aluminum as an important building block for the development of a multiscale method that couples an atomistic model with discrete dislocation dynamics in 3d (\eg CADD3d). Straight dislocations of arbitrary charac ...

The coupled atomistic/discrete-dislocation method in 3d. Part III: Dynamics of hybrid dislocations

Toward a 3D coupled atomistic and discrete dislocation dynamics simulation: dislocation core structures and Peierls stresses with several character angles in FCC aluminum

Jean-François Molinari, Guillaume Anciaux, Till Junge, Jaehyun Cho

We present a robust method to obtain the displacement field of a dislocation core, which is one of the building blocks for the development of a direct multiscale method coupling an atomistic domain to a discrete dislocation dynamics engine in 3D (e.g. CADD ...
